PlCKLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 545,412, dated August 27, 1895.

Application filed January 18, 1895. Serial Nn. 535,402. (No model.)

To all whom it may concern:

Be it known that I, LOUIS N. MCCARTER, a citizen of the United States, and a resident of Norristown, Montgomery county, Pennsylvania, have invented certain Improvements in Rohling-Machines, of which the following is a specification. i

My invention relates particularly to machines for handling black plate during the pickling operation of tin-plate manufacturing.

The main object of my invention is to so construct the machine that the crates for the plates can be shifted from a stationary rail onto the movable rail of the machine and the plates carried by the trays can b'e immersed in liquor and agitated therein and removed therefrom by mechanism under the control This object I attain in the following manner, reference being had to the accompanying drawings, in which- Figurel is a plan view of my improved machine for pick1ing-metal plates. Fig, 2 is a front view. Fig. 8 is a side view showing one of the vats in section. Fig. 4 is a section on the line 4 4, Fig. l. Fig. 5 is a section on' the line 5 5, Fig. l; and Fig. 6 is a' perspective view of one of the crates. Fig. 7 is a view in section through the rim of one of the pocket-wheels. v

A is the frame of the machine.

B B are the vats, two in the present instance. A

D is the removable rail suspended from the machinev and when in the raised position, as shown by dotted lines in Fig. 2, aligns with the x'ed rail D', extending through the factory building, so that the trays C, which are suspended from the rails, can be moved from one point to the other of the factory'ioaded, dipped, and unloaded, requiring very little manual labor.

The crates in the present instance consist of the platform c, the frame c', and the two heads o8 c3. Vertical standards c2 at each v corner connect the frame to the platform, and

each pair of standards carry a head c3, and adapted to each head isv a hanger c", havinga wheel c5, adapted. to the rail.' It will be understood that other forms of crates may be used without `departing from my invention.

In this crate the plates are arranged on end,

as shown in Fig. 3, on the 'platform and extend up through the frame c', so that a number of plates can be immersed at once. The rail D is attached to two chains d. d, in the crates is moved onto the rail D from the fixed' .rail D', and a lever operated, the rail with the crate is lowered, so as to allow the crate to enter one ofthe vats B B. ing out the lever and throwing in another 1ever the crate is given a vertical reciprocating ypresent instance, and each chain has a coun-v Then by throwmotion in the vat, so as to keep the liquid ytherein in constant agitation. After the crate has been in the vat a certain length of time another lever is shifted, which raises the rail D to its normal position in line with the rail- D and removes the tray from the vat. l

The mechanism for imparting the abovedescribed motion is constructed as follows: F is the driving-shaft, having'abelt-pulley f,

and on this shaft is secured a pinion f', gearing with' a wheel g, fixed on an intermediate shaft G. Loose on the shaft G are two pinions g g2. The pinion g carries one part of a fricf tion-clutch G', andthe pinion g2 carries one part of the friction-'clutch G2. l The other part of each clutch, in the present instance, is carried by a hub G3, splined to vthe shaft G, so that'itwill slide on but turn with the shaft. H'is a shifter-rod, having a fork h engaging with the hub G3. This shifter-rod 'H is controlled by a lever H', pivotedat h' at the side of the machine, so that by operating the lever y the hub Grs can be .thrown into engagement with either of the lfriction-clutches G or G2, or can be moved midway'between the two, as shown in the drawings. The pinion g meshes v directly with the gear-wheel c on the shaft E',

while the pinion g2 meshes indirectlywith a wheel e through an intermediate pinion e2 on a stud e3, projecting from the frame of the machine, as clearly illustrated in Fig.- 4, so that when the shaft E is in gear with' the shaft G through vthe wheels e g the crates will be elevated by the mechanism, and when the clutchhnh is thrown over, so as to place the shaft E in gear with the shaft G through the train of wheels e', e2, and g2, the shaft E will be reversedv and the crates lowered. Loose on the driving-shaft F is a pinion f'-, carrying one section of a frictionclutch F', the other section being carried by a hub F2, splined to the shaft, so that it will turn with but slide thereon. This hub is controlled bya shifterrod I, having a fork z' engaging with the hub.

I is a lever pivoted at i to the frame of the machine at the side thereof and connected to the shifter I, so that on operating the lever the hub F2 can be thrown into and out of contact with the section carried by the pinion f2. This pinion. f2 meshes with a gear-wheel j, secured to a shaft J, mounted in bearings in the frame. On the end of this shaft is an eccentric J.

J 2 is an eccentric-rod having'a strap j', encircling the eccentric J', andthe opposite end of the eccentric-rod has a hook '2, adapted to engage the pin e4 on a disk E2, secured to the shaft E', so that when the eccentric-shaft is in gear with the driving-shaft and the eccentric-rod hooked onto the pin of the disk E2,

the shaft E will be given a rocking motion, causing the crates to rise and lower in the vats and thus agitate the liquor, thus insuring the proper treatment of the plates while in the liquor. Y

In order to throw the eccentric-rod out of engagement with the pin of the disk E2, I connect the hooked end of the rod by `a link la to one arm of a lever K, pivoted at lo' to a stud on the side of the machine. The handled end of the lever is preferably provided with a spring-pawl k2, which is adapted to notches in a segment k3, fixed to the side of the machine. As shown in Fig. 3, the eccentric-rod is in engagement with the pin of the disk E2 and the shaft E is not in gear with the intermediate shaft G, so that the agitating motion is given to the crates. I preferably arrange a stopa. on the frame of themachine and a lug c on the disk E2, which is adjustable in a slot in said disk, so that the stop will limit the downward movement of the crates, and I also provide dash-pots a', into which extend the plungers a2 from the counterbalance-weights d', so that the trays p when lelevated will' not come to a sudden stop.

On the shifter-rod H are two arms h2 ha, and on the wheel e are lugs e e7. As the crates are lowered into the vats and when they reach the lowermost point, the lug c7 strikes the shifter-arm h8 and shifts the clutchcrates are elevated to their extreme position, so that the rail D will align with the rail D',

' the lug e strikes the shifter-arm h2, throwing extent. Bycounterbalancing--the crates, as' shown, very little power is required to operate the machine. I preferably mount a flywheel i3 on the shaft J, so as to carry the eccentric over the center.

I prefer to make the crates as shown in Fig. 6. and the platform c has cross-bars, while the frame c' has longitudinal bars, and connecting the barsrof the platform to the vbars of the frame are vertical bolts c5, riveted. in position, these bolts serving to hold the parts together, at the same time acting as partitions for the plates, as shown in Fig. 3.

The operation of the machine is as follows: vWhen the rail D is elevated, as shown by dotted lines in Fig. 2, it aligns with the rail D', and a crate loaded with plates is pushed onto the rail D and the lever H' is shifted so as to allow the rail D to lower tothe position shown in Fig. 3. The stop a will limit the downward movement and a shifter will be automatically thrown so as to release the shaft E from the control of the shaft G. The eccentric-rod is then thrown into gear, as shown in Fig. 3, by the lever` K, and the lever 1 throws the eccentric-shaft .I in gear with the driving-shaft, so that a vertical reciprocating motion is given to the crate in the vat to agitato the liquor therein and to cause it to come into contact with all parts of the plate. When the plates have been in Vthe liquor a certain length of time, the eccentric-shaft is thrown ont of gear and the eccentric-rod is moved out of contact with the pin on the disk E2. The lever H is then moved to such a position that the shaft Eis thrown into gear with the shaft G through the return gear, so as to elevate the rail D and the crate clear of the vat and .in line with the rail D. The first vat B is the pickling-vat, while the second vat is the rinsing-vat, and when the crate is removed from the first vat it is trav ersed on the rail until above the second vat, when another crate of plates is shifted onto the rail and the above described operation is repeated, one tray being in the pickling-vat while the other tray of plates is being cleansed. In order to stay the rail- D, I connect it to a series of rods LDL-three in the present instance-which pass through openings in the They are preferably'. made of copper.

frame A of the machine and have at their the stops and the frame I preferably mount lspring-buers d5 to take up -the shock and thus relieve the stop a when the rail is low-V -ered. Stops 'd6 on the railD come in contact j with the rail D when itis elevated.v
